产品描述
9,10-蒽二基-双(亚甲基)二甲酸(9,10-Anthracenediyl-bis(methylene)dimalonic Acid, ABDA),是一款测定单线态氧(1O2)的指示剂,具有比 9,10-蒽二基-二-二丙酸更好的特性。这一水溶性的蒽衍生物与单线态氧反应,光漂白生成对应的内过氧化物(见下图),这一反应通过分光光度法记录400nm处光密度的降低来监测[1-2]。

实验方法:通过化学探针- 9,10-anthracenediyl-bis(methylene)dimalonic acid (ABMDMA)的光漂白特性来测定光诱导的单线态氧生成。
Fig Photobleaching of 0.15 mM 9,10-anthracenediyl-bis(methylene)dimalonic acid (ABMDMA) by singlet oxygen generated by (i) void silica nanoparticles as control; (ii, iii) 2 μM Pc4SNP and Pc4 water solution. The change in ABMDMA absorption at 400 nm was measured as a function of irradiation time. Inset: absorption spectra of 0.15 mM ABMDMA water solution containing 2 μM Pc4SNP as a function of irradiation times (0 to 360 sec). Values are the means ± SEM (n = 3).
